                              are bolted to the mobile platform, while the third is bolted to
                              the framework itself using a predrilled hole on the framework.
                              Figure 3-2 shows where to drill holes in each of the 2-inch
                              aluminum pieces.
                                 To begin installing the batteries, first take two of the 2-inch
                              pieces of aluminum angle and bolt one to each side of frame-
                              work connecting piece B using two 5/32-inch bolt, nut, and
                              lockwasher sets for each. There are two predrilled holes on
                              each side of the upper framework. Next slide one of the batter-
                              ies under each of the pieces making sure that the battery ter-
                              minals face the front of the platform and that they are sitting
                              in their correct mounting positions. Then place two more alu-
                              minum pieces, with their mounting holes flush with the robot’s
                              platform, snug against the battery. Place one piece against the
                              front of the battery and one against the side; do this to both
                              batteries.
                                 Mark the mounting holes on the platform where each of
                              the four aluminum pieces sit. Remove the pieces and battery
                              and drill the four 5/32-inch-diameter holes in the platform
